I am arriving at the table for all of this a bit late, but hopefully I can still get my 42 cents in.
As per my post on the DAPPCRAFT HQ bid thread, I feel this Proposal is making the very dangerous mistake of mixing together trying to incentivize Players and trying to incentivize Voters.
First, I want to give props to the fact that the MetaGamiMall has indeed been holding the record of the most populated scene for some time.
The layout of the scene itself is quite nice, and the whole premise of having wearables on display and portals to other scenes is rather visionary.
It should be indeed a good idea to try to put in place a system for incentivizing Players. I do believe MANA Coupons could be tied into this somehow, as it would also be a way of rewarding / incentivizing Creators.
